Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a soundproofing and vibrationproofing sheet that can be used for walls, floors, and ceilings in general houses and the like.

[Background technology]

In the past, there was no material used for floors and ceilings in ordinary houses or apartment complexes (especially in residential buildings, etc.) that had both soundproofing and vibrationproofing properties. For example, in recent years,
Barrier materials that are said to be effective against noise pollution (soft sound insulation sheets made by mixing h-density substances such as lead powder in metal plates such as lead plates or synthetic resins, or foam type) Concrete, etc.) have been widely used, but the sound generated in the eastern part or the sound from upstairs is transmitted to downstairs accompanied by vibration.
So-called (2) body-transmitted sounds were not prevented.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned conventional drawbacks, and it is an object of the present invention to provide a soundproof and vibration-proof sheet that has both the function of blocking internal and external noise and the vibration-proofing effect against impact noise or vibration sound. .

[Disclosure of the invention]

Hereinafter, the present invention will be explained in detail with reference to the drawings.

In the figure, 1 is a wooden material, 2 is a soft sound insulating sheet, 6 is a resin foam, and 4 is a decorative surface material.

A large number of recesses 5 are bored in the surface of the wooden material 1, and the recesses 5 are filled with a resin foam 6 such as foamable cyclized vinyl, urethane, synthetic rubber, or the like. Both sides of wood material 1 are joined to make it easier to join.

It may be modified.

The surface of the wooden material 1 with the resin foam 3 filled in the recess 5 is coated with a thermoplastic resin such as polycyclized vinyl, polyethylene, polypropylene, etc., or metal powder such as lead powder, iron powder, etc., or gold powder such as barium sulfate. A soft sound insulating sheet 2 mixed with specific gravity substances to have a specific gravity of 2 or more is pasted, and one side of the soft sound insulating sheet 2 is made of plywood or a synthetic resin puylum with a pattern to give it a wood feel. A surface decorative material 4 such as the above is attached and integrated.

〔Effect of the invention〕

As described above, the soundproofing and vibrationproofing panel of the present invention has a large number of recesses on the surface of the wooden material, fills the recesses with resin foam, and affixes a soft sound insulating sheet to the surface of the wooden material. Since the surface decorative material is attached and integrated, the soft sound insulating sheet prevents the transmission of noise, and the resin foam has the effect of absorbing impact and vibration sounds, making it ideal for walls in general houses, etc. It is useful as a soundproofing and vibrationproofing panel for floors, ceilings, etc.
